"The remote host is affected by the vulnerability described in GLSA-200605-10
(pdnsd: Denial of Service and potential arbitrary code execution)
The pdnsd team has discovered an unspecified buffer overflow
vulnerability. The PROTOS DNS Test Suite, by the Oulu University Secure
Programming Group (OUSPG), has also revealed a memory leak error within
the handling of the QTYPE and QCLASS DNS queries, leading to
consumption of large amounts of memory.
Impact :
An attacker can craft malicious DNS queries leading to a Denial of
Service, and potentially the execution of arbitrary code.
Workaround :
There is no known workaround at this time."
